This behavior vindicates the behavior of the Taliban themselves. They were/are famous for shaving off heads of people who actually shaved their beards. This convent school is doing the opposite. Also proves the point that at the end of the day, every form of government is dictatorial, its just the election process that is different.
This is the after effect of living in a county of dictators.. Please understand that this is the rule that was implemented by a school for its students. The school officials did not roam around the country side and insist that everybody should be clean shaven and take action if they did not follow their suggestion.
